Saturated liquid water enters a well-insulated pump at 15kPa and is reversibly compressed to 10 MPa. Calculate the specific pump work input for this isentropic compression using three methods:
a) Steady flow energy balance, connecting states (1) and (2) using entropy data from the tables
b) Reversible flow work equation with the inlet specific volume and the pressure values
c) Reversible flow work equation with the average specific volume and the pressure values
